Astronomy Cake

For my son, telescope in center, planets on top; he is an astrophotographer. Stars and columns light up... Top is space, bottom is earth/grass. BTW, top is foam, not real cake for two reasons: 1.) We had other desserts so excess cake wasn't needed 2.) Nobody wants to eat all that black icing. In yellow icing around the bottom of the cake it says "Never stop looking to the stars" ;-)
